To a solution of tert-butyl (R)-1-((3,5-difluoro-4-(1-methoxy-2-methylpropan-2-yl)phenyl)carbamoyl)-6-methoxy-3,4-dihydroisoquinoline-2(1H)-carboxylate (200 mg, 0.40 mmol) in ethyl acetate (3 mL) was added 4M hydrogen chloride/ethyl acetate (4 mL) at room temperature, and the mixture was stirred overnight. The reaction mixture was concentrated under reduced pressure to give (R)—N-(3,5-difluoro-4-(1-methoxy-2-methylpropan-2-yl)phenyl)-6-methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxamide hydrochloride (175 mg, 0.397 mmol, 100%) as white crystals.
